| Popis: | The clinical and histological aspects of socket healing have been reported (Boyne 1966, Trombelli et al. 2008; Van der Weijden 2009, Moya-Villaescusa & Sanchez-Perez 2010, Ten Heggeler et al. 2011). Alveolar bone resorption post-extraction varies among individuals and sites; ridge height loss is greater in mandibular than maxillary sites and ridge width loss is greater on buccal aspects (Smukler et al. 1999, Iasella et al. 2003). Post-extraction ridge resorption leads to loss of function, inadequate bone for dental implants and prosthodontic difficulties (Bartee 2001). The need to avoid such complications has spurred significant interest in developing techniques and biomaterials to prevent ridge resorption. Alveolar ridge preservation (ARP) is a guided bone regeneration (GBR) procedure aiming to control post-extraction ridge resorption. Current ARP protocols include bone autografts, allografts, xenografts, alloplasts and membranes of diverse origin (Nemcovsky & Serfaty 1996, Bartee 2001, Iasella et al. 2003, Fickl et al. 2008a,b). Despite numerous options, outcome data are scarce (Ten Heggeler et al. 2011). The limited evidence available suggests that mineralized freeze-dried bone allograft (FDBA) combined with collagen membrane may offer the best height preservation (Iasella et al. 2003, Ten Heggeler et al. 2011). No ARP protocol effectively prevents ridge width changes (Ten Heggeler et al. 2011). To the best of our knowledge, there are no studies providing insights regarding the factors, anatomical or other, which determine ARP outcomes. Therefore, the purpose of this study was to investigate and compare, in maxillary and mandibular sites, the clinical and histological outcomes of ARP, in an effort to identify treatment outcome determinants for these different anatomical locations. |
